Thankyou Massimo and DenesL, Denesl, I know MSSQL has its own python ODBC package (pymssql?) , so I've never been sure if the "mssql:..." reference is really using pyODBC, or another package. I was expecting to see pyODBC explicitly referenced, as it is in a simple python scipt's connection string. If what you say is true, then each database type that uses pyODBC will need its own prefix type in the connection string. I expect that's what Massimo refers to by an "Adaptor".
Massimo, looking forward to hearing from you. Regards Andrew
